System and method for managing related information of multimedia programs

Abstract

A method for a first electronic device and a second electronic device to manage related information of a multimedia program. The method obtains decoded data of ultrasound signals when the first electronic device receives the ultrasound signals from the second electronic device. The method further receives a query keyword input from the first electronic device. When the received query keyword matches the decoded data, the related information of the multimedia program is displayed on the first electronic device.

 obtaining decoded data of ultrasound signals by decoding the ultrasound signals according to a preset modulation method, when the first electronic device receives the ultrasound signals from the second electronic device using a microphone of the first electronic device;   receiving a query keyword input from the first electronic device;   determining whether the received query keyword matches the decoded data; and   displaying related information of a multimedia program in the decoded data on a display screen of the first electronic device, when the received query keyword matches the decoded data.   
     
     
         2 . The method as described in  claim 1 , further comprising:
 encoding the related information of the multimedia program by the second electronic device, when the second electronic device receives the multimedia program from a television station in communication with the second electronic device;   converting the encoded related information into the ultrasound signals by the second electronic device according to the preset modulation method; and   outputting the ultrasound signals to the first electronic device by the second electronic device.   
     
     
         3 . The method as described in  claim 2 , wherein the related information is encoded into a packet which stores an identifier of the packet to represent the related information, specific nouns in the multimedia program, content descriptions of the specific nouns, and a length of the content descriptions. 
     
     
         4 . The method as described in  claim 3 , wherein the content descriptions of the specific nouns in the decoded data is displayed when the received query keyword matches the decoded data. 
     
     
         5 . The method as described in  claim 1 , furthering comprising:
 displaying a failure message of the received query keyword on the display screen, when the received query keyword does not match the decoded data.   
     
     
         6 . The method as described in  claim 3 , further comprising:
 determining that the received query keyword matches the decoded data, when the received query keyword is the same as one of the specific nouns in the decoded data; or   determining that the received query keyword does not match the decoded data, when the received query keyword is different from each of the specific nouns in the decoded data.   
     
     
         7 . An electronic device for managing related information of a multimedia program, the electronic device comprising:
 at least one processor; and   a computer-readable storage medium storing one or more programs, which when executed by the at least one processor, the one or more programs comprising causes the at least one processor to:   obtain decoded data of ultrasound signals by decoding the ultrasound signals according to a preset modulation method, when the electronic device receives the ultrasound signals from a sender device using a microphone of the electronic device;   receive a query keyword input from the electronic device;   determine whether the received query keyword matches the decoded data;   display related information of a multimedia program in the decoded data on a display screen of the electronic device, when the received query keyword matches the decoded data.   
     
     
         8 . The electronic device as described in  claim 7 , wherein the one or more programs further comprising causes the at least one processor to:
 encode the related information of the multimedia program, when the multimedia program is received from a television station in communication with the electronic device;   convert the encoded related information into the ultrasound signals according to the preset modulation method;   output the ultrasound signals.   
     
     
         9 . The electronic device as described in  claim 8 , wherein the related information is encoded into a packet which stores an identifier of the packet to represent the related information, specific nouns in the multimedia program, content descriptions of the specific nouns, and a length of the content descriptions. 
     
     
         10 . The electronic device as described in  claim 9 , wherein the content descriptions of the specific nouns in the decoded data is displayed when the received query keyword matches the decoded data. 
     
     
         11 . The electronic device as described in  claim 7 , wherein the one or more programs further comprising causes the at least one processor to:
 display a failure message of the received query keyword on the display screen, when the received query keyword does not match the decoded data.   
     
     
         12 . The electronic device as described in  claim 10 , wherein the received query keyword is determined to match the decoded data, when the received query keyword is the same as one of the specific nouns in the decoded data; or
 the received query keyword is determined to not match the decoded data, when the received query keyword is different from each of the specific nouns in the decoded data.   
     
     
         13 . A non-transitory computer readable storage medium having stored thereon instructions that, when executed by a first electronic device and a second electronic device, causes the first and the second electronic device to perform a method for managing related information of a multimedia program, the method comprising:
 obtaining decoded data of ultrasound signals by decoding the ultrasound signals according to a preset modulation method, when the first electronic device receives the ultrasound signals from the second electronic device;   receiving a query keyword input from the first electronic device;   determining whether the received query keyword matches the decoded data; and   displaying related information of a multimedia program in the decoded data on a display screen of the first electronic device, when the received query keyword matches the decoded data.   
     
     
         14 . The non-transitory computer readable storage medium as described in  claim 13 , further comprising:
 encoding the related information of the multimedia program by the second electronic device, when the second electronic device receives the multimedia program from a television station in communication with the second electronic device;   converting the encoded related information into the ultrasound signals by the second electronic device according to the preset modulation method; and   outputting the ultrasound signals to the first electronic device by the second electronic device.   
     
     
         15 . The non-transitory computer readable storage medium as described in  claim 14 , wherein the related information is encoded into a packet which stores an identifier of the packet to represent the related information, specific nouns in the multimedia program, content descriptions of the specific nouns, and a length of the content descriptions. 
     
     
         16 . The non-transitory computer readable storage medium as described in  claim 15 , wherein the content descriptions of the specific nouns in the decoded data is displayed when the received query keyword matches the decoded data. 
     
     
         17 . The non-transitory computer readable storage medium as described in  claim 13 , furthering comprising:
 display a failure message of the received query keyword on the display screen, when the received query keyword does not match the decoded data.   
     
     
         18 . The non-transitory computer readable storage medium as described in  claim 15 , further comprising:
 determining that the received query keyword matches the decoded data, when the received query keyword is the same as one of the specific nouns in the decoded data; or   determining that the received query keyword does not match the decoded data, when the received query keyword is different from each of the specific nouns in the decoded data.
